Abstract: A system includes an illumination source, a detector and a processor. The detector acquires spectral measurements of a sample under test under at least one varying condition. The processor processes the measurements to generate at least one spectral representation that includes Raman spectra and at least one spectral representation that includes non-Raman spectra.

Abstract: Polarization selective surface enhanced Raman spectroscopy (SERS) includes a plurality of nanofingers arranged as a SERS multimer to exhibit a polarization-dependent plasmonic mode and one or both of a stimulus source and a Raman detector. The stimulus source is to illuminate the SERS multimer with a stimulus signal and the Raman detector is to detect a Raman scattering signal emitted by an analyte in a vicinity of the SERS multimer. One or both of the Raman scattering signal has a polarization state dictated by or associated with the polarization-dependent plasmonic mode and the stimulus signal has a polarization state corresponding to the polarization-dependent plasmonic mode.

Abstract: A scattering spectroscopy nanosensor includes a nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte when interrogated by an optical stimulus. The scattering spectroscopy nanosensor further includes a protective covering to cover and protect the nanoscale-patterned sensing substrate. The protective covering is to be selectably removed by exposure to an optical beam incident on the protective covering. The protective covering is to prevent the analyte from interacting with the nanoscale-patterned sensing substrate prior to being removed.

Abstract: A light modulator includes a light guide to guide light by total internal reflection, a diffraction grating at a surface of the light guide, and a liquid crystal in contact with the diffraction grating. The liquid crystal has a first state with a first refractive index that substantially matches a refractive index of a material of the diffraction grating to defeat the diffractive coupling. The liquid crystal has a second state with a second refractive index that differs from the first refractive index to facilitate the diffractive coupling.

Abstract: A light modulator includes a light guide to guide light, a diffraction grating at a surface of the light guide, and a fluid having a refractive index substantially matched to a refractive index of the diffraction grating. The diffraction grating is to couple out a portion of guided light from the light guide using diffractive coupling. The index-matched fluid is to be selectively moved both into contact with the diffractive grating to defeat the diffractive coupling and out of contact with the diffraction grating to facilitate the diffractive coupling to modulate the coupled out guided light.

Abstract: According to an example, methods for forming three-dimensional (3-D) nano-particle assemblies include depositing SES elements onto respective tips of nano-fingers, in which the nano-fingers are arranged in sufficiently close proximities to each other to enable the tips of groups of adjacent ones of the nano-fingers to come into sufficiently close proximities to each other to enable the SES elements on the tips to be bonded together when the nano-fingers are partially collapsed. The methods also include causing the nano-fingers to partially collapse toward adjacent ones of the nano-fingers to cause a plurality of SES elements on respective groups of the nano-fingers to be in relatively close proximities to each other and form respective clusters of SES elements, introducing additional particles that are to attach onto the clusters of SES elements, and causing the clusters of SES elements to detach from the nano-fingers.
